Sažetak
Almost every pharmaceutical presents a potential hazard to the environment. Because of that, they are listed as an emerging pollutant. Their properties such as chemical stability, toxicity to microorganisms and general recalcitrance towards degradation are the reason of becoming ubiquitous in the environment. Wastewater treatment plants in most cases are showing low efficiency for the removal of emerging pollutants and some other options have to be considered. This study involves UV-C/H2O2 and UV-C/S2O8 2- advanced oxidation processes, applied for the treatment of pharmaceuticals etodolac and febuxostat. The apparent degradation kinetic constants of each of these two pharmaceuticals were calculated. The degradation of pharmaceuticals by both investigated photooxidative processes obeyed first-order kinetics. The influence of pH and pollutant/oxidant ratio on the degradation kinetics was evaluated using the full factorial experimental design. The optimum treatment conditions were deduced by the response surface modeling. In both cases, degradation kinetics is dependent on both pollutant/oxidant ratio and pH.
